US Patent:

59484470, Sep 7, 1999
Filed:

Apr 10, 1996
Appl. No.:

8/630800
Inventors:

Stephen C. McHaney - Odessa TX
Steven L. Oetting - Midland TX
Karl L. Herzog - Odessa TX
Assignee:

Huntsman Polymers Corporation - Salt Lake City UT
International Classification:

B29B 730
US Classification:

425171
Abstract:

A method and apparatus for product recovery of polyolefins, particularly high molecular weight amorphous poly alphaolefins, wherein the use of water during the method is significantly decreased and wherein the intermediate stage of storing and drying the chunk form of the polyolefin is eliminated. Polyolefins produced in a reactor are heated and mixed by sigma blades in a kneader-extruder to remove any unreacted monomer(s). The polyolefin material in a liquid form is then transferred directly to an extruder to further remove any unreacted monomer(s) and catalyst(s). The invention further includes a method of measuring the inventory in a vessel using a gas of known quantity and known thermodynamic properties.

International Classification:

C09J 123/14
Abstract:

A process for reducing unreacted monomers and condensable and non-condensable hydrocarbon fractions in an APAO which includes introducing molten APAO into heated and insulated jacketed pipe while injecting a stripping agent based on the total weight of the contents of the jacketed pipe; maintaining the stripping agent with the molten APAO stream from ten seconds to ten minutes, forming a flowable heated mixture at 250 to 450 degrees Fahrenheit in the heated and jacketed pipe forming a flowing heated mixture; and passing the flowing heated mixture through a thin film evaporator assembly, while maintaining the temperature of the flowing heated mixture, stripping the organoleptic species and acids and volatile organic components from the flowing heated mixture and removing and recovering a condensable fuel fraction and a non-condensable hydrocarbon gas with energy, while simultaneously forming an odor-reduced, cleaned molten APAO-based HMA.
